Tajikistan was a constituent (union) republic of the Soviet Union from 1929 until its independence in 1991. The capital is Dushanbe. Several ethnic ties and outside influences complicate Tajikistan’s national identity to a greater extent than in other Central Asian republics. The Tajik people share close kinship and their language with a much larger population of the same nationality living in northeastern Afghanistan, whose population also includes a large proportion speaking Dari, a dialect of Persian intelligible to Tajiks. Despite sectarian differences (most Tajiks are Sunni Muslims, while Iranians are predominantly Shīʿites), Tajiks also have strong ties to the culture and people of Iran; the Tajik and Persian languages are closely related and mutually intelligible. The Tajiks’ centuries-old economic symbiosis with oasis-dwelling Uzbeks also somewhat confuses the expression of a distinctive Tajik national identity. Since the early years of independence, Tajikistan has been wracked by conflict between the government and the Islamic opposition and its allies.
